window manufacturers and installers

Window installation is particularly important. The best windows on the market are worthless if they aren’t installed properly. Look for well trained and certified professionals.

Large and small manufacturers

There are thousands of manufacturers of windows, doors and skylights. Most of them are small manufacturers, producing and selling at a rather local scale. Some small manufacturers may have great windows, but choosing a popular and large manufacturer – instead of a small and unknown one - may be a clever option, or at least a good starting point.

Pay also attention to the fact that all manufacturers have different types and models of windows, involving different prices and qualities. Take that into account, and compare their windows using the Energy Star-NFRC window rating.

Installation & Installers

Window installation is particularly important. Do not install the windows (or doors, or skylights) yourself, unless you are absolutely sure of what your are doing.

Hire a well trained professional. Ask him about professional certifications. The risk of condensation, water damage and leaks are too high to act otherwise.
